Altitude Display Discrepancy

[drdickie 2]

I was cruising at FL360 in the 747-8i freighter and noticed that the altitude on the ATT was 1000 feet higher, even though the ribbon shows 358 below and 362 above the altitude display. Sorry if this has been reported before, but I could not find it on the forum. Screenshot attached.

Impossible to tell...we need to see the Altimeter settings on your PFD & Standby Instrument to be sure you have STD set.Kind RegardsSteve

Both barometric settings were 29.92. Sorry I forgot to include that. But, please note the tape readings under and above 37100. So, it's more than a barometric setting.
